Nitrogen oxides (NO x ) monitoring requires sensor platforms that deliver ppb-level sensitivity, ambient-temperature operation, and molecular discrimination. However, rapid and selective NO x detection at room temperature remains elusive. Although 2D transition metal carbides/nitrides (MXenes) show promise in chemiresistive sensing, their susceptibility to ambient degradation and poor selectivity limit practical deployment. Here, a room-temperature NO x sensor is developed by epitaxially growing Hofmann-type metal–organic frameworks (Ni-pyz) on oxygen-terminated monolayer large-size MXene (Ti 3 C 2 T x ). The Ni-pyz/Ti 3 C 2 T x heterostructure exhibits enhanced sensitivity (4.8 and 5.5 times compared to Ti 3 C 2 T x ) and low detection limits (8.8 and 6.9 ppb) for NO and NO 2 , along with high selectivity and good stability (>85% response after 8 weeks). The enhanced sensitivity results from electronic coupling between the Ti 3 C 2 T x and Ni(CN) 4 , promoting charge transfer with NO x . The improved selectivity arises from the pore confinement effect of Ni-pyz and the specific adsorption of NO x through Lewis acid-base interactions with open Ni sites. Importantly, the dynamic response of Ni-pyz/Ti 3 C 2 T x closely mirrors that of a trace-level chemiluminescence NO x analyzer at low NO x concentrations, enabling high-temporal-resolution, long-term atmospheric monitoring. This functional strategy overcomes the insufficiency of MXene-based gas sensors, paving the way for the development of high-performance sensors.

The Advanced Oxidation Process (AOPs) has garnered significant attention as an efficient and promising technology for wastewater treatment in the field of environmental remediation. Currently, the exploration of highly effective catalysts for peroxymonosulfate (PMS) activation remains a focal point of scientific research, with increasing emphasis placed on the reuse of waste materials. In line with this objective, this study reports the synthesis of a Fe Co bimetallic metal-organic framework (MOF)-sponge composite (FCS) via an in-situ growth method using discarded natural sponge as a support material. Subsequently, the carbonized derivative (FCSC), obtained through high-temperature carbonization, was employed as a catalyst for PMS activation. The resulting catalyst demonstrated remarkable efficiency in removing 4-nitrophenol (4-NP) from aqueous solutions. Utilizing waste natural sponge as a support not only facilitates resource recovery but also enables the uniform distribution of MOF particles within its inherent three-dimensional porous structure. This feature enhances the contact between the catalyst and pollutants, thereby improving catalytic performance. Moreover, diatomic active sites exhibit significantly higher degradation efficiency toward 4-NP compared to the monometallic configurations. This enhanced performance can be attributed to the more rapid generation of free radicals by diatomic structures during PMS activation, which accelerates electron transfer between metal centers and adjacent oxygen atoms. This work offers novel insights into the development of efficient strategies for the removal of organic contaminants.

Biodegradable poly(lactic acid) (PLA) nanofibrous membranes (NFMs) alleviate plastic pollution and attract attention in particulate matter (PM) filtration. However, they lack gas selectivity, and their poor electroactivity coupled with rapid charge dissipation leads to unstable PM filtration efficiency, which hampers their further development. Herein, we employed a microwave-assisted method to fabricate high-selectivity active nanocrystals (HSANs), and integrated them into PLA NFMs via a combined electrospinning-electrospray strategy, yielding HSA-PLA NFMs with a hierarchical porous structure. With uniform HSANs anchoring (3, 6 and 9 wt%), the obtained HSA-PLA NFMs showed increased surface potential (up to 8.3 kV), dielectric constant (1.71) and porosity (95.6 %). They exhibited excellent CO 2 adsorption and HSA-PLA9 reached 1.9 mmol·g −1 at 273.15 K/1.0 bar. Its CO 2 /N 2 selectivity was confirmed by IAST/breakthrough tests and the mechanism analyzed via three isothermal models. Moreover, endowed with pronounced activity and optimized morphology, HSA-PLA NFMs exhibited PM 2.5 and PM 0.3 filtration efficiencies of 99.7 % and 99.3 % at 85 L/min, remarkably outperforming Pure PLA (only 84.9 % and 83.9 %). This strategy integrates CO 2 adsorption and PM filtration, thereby facilitating the development of eco-friendly multifunctional permselective membranes for simultaneous purification.

The anodic oxygen evolution reaction (OER) is a critical yet kinetically sluggish half-cell process in water electrolysis and metal-air batteries. This study proposes an innovative approach to sustainable resource recycling and the synthesis of self-supported metal-organic framework (MOF) electrocatalysts in a single step. The utilization of recycled stainless steel mesh (SSM) as both a substrate and a self-sacrificial template facilitated the successful engineering of the deposition of crystalline FeNi-MOF-74 ( FeNidobdc ) with homogeneous morphology, designated as FeNidobdc/SSM (1, 6, 12, 24, and 36 h, labeled FeNidobdc/SSM 1 to 5). Among them, the optimal FeNidobdc/SSM4 catalyst demonstrated exceptional OER performance, featuring a low Tafel slope (63.9 mV dec −1 ), a low overpotential (η 10 = 210 mV), and prolonged stability (31.8 h current retention). The enhanced electrocatalytic performance of the material can be attributed to several factors, including the high porosity and mesoporous structure of the MOF, the optimized Fe/Ni content, the multi-metal doped lattice, and the inherent stability of the SSM substrate. The use of SSM not only provides a self-supported framework but also enables in situ sacrificial growth, thereby enhancing interfacial binding and long-term cycling stability. Furthermore, the abundance of SSM offers a sustainable source of Fe and Ni, making it an ideal template for OER catalysis, while the self-supported design simplifies preparation steps by eliminating the need for additional binders or conductive agents. This study establishes a new pathway for sustainable resource recycling and one-step synthesis of high-performance, self-supported MOF electrocatalysts for OER applications.

Constructing heterojunctions to suppress the recombination rate of electron−hole pairs is an effective method for improving photocatalytic efficiency. However, the transfer rate of active species has rarely drawn attention. In this study, a nanoporous CoY-MOF photocatalyst with a channel transfer effect is developed. It is formed by one Co 3+ ion, one Y 3+ ion, and three deprotonated pyridine carboxylate ligands through coordination bond. Furthermore, a Z-scheme heterojunction CoY-MOF/AgCl composite photocatalyst is successfully constructed by coupling the nanoporous CoY-MOF with AgCl. The heterojunction interface of CoY-MOF/AgCl enhances significantly the separation efficiency of photogenerated electrons and holes, utilizes effectively charge carriers, and strengthens photocatalytic performance. More importantly, the channel transfer effect of the nanoporous MOF promotes the rapid migration of active species, increasing the transfer rate of reactants to the active species. The synergistic effect of these two aspects further improves the degradation efficiency of organic pollutants. Under visible light irradiation, the degradation efficiency of tetracycline (TC) for CoY-MOF/AgCl-35 within 21 min is approximately 87.56 %, which is higher than that of pure CoY-MOF (47.80 %) and AgCl (54.42 %). This paper provides a new strategy for constructing highly efficient heterojunction engineering in photocatalysis.

Foodborne Listeria monocytogenes ( L. monocytogenes ) poses a serious threat to public health, yet conventional detection methods remain time-consuming and lack sufficient sensitivity for complex food matrices. To address this gap, a Tb 3+ -doped mixed-valence cerium-based metal–organic framework (Tb 3+ @MVCM) was developed as a dual-functional probe via in situ partial oxidation of cerium-based metal–organic frameworks (Ce-MOFs) followed by Tb 3+ doping. This probe exhibits both fluorescence emission and redox activity. Based on this, we designed a dual-recognition, dual-mode aptasensor combining the Gram-positive bacteria binding capability of vancomycin (Van) with the specific molecular recognition of nucleic acid aptamers (Apt). The fluorescence signal of the Apt/Tb 3+ @MVCM–Van/Fe 3 O 4 –L. monocytogenes complex enabled highly sensitive detection with a limit of detection (LOD) of 5.19 CFU/mL, while the residual probe catalyzed a colorimetric reaction yielding an LOD of 6.48 CFU/mL. The analytical performance of this strategy was further validated using real tap water and milk samples, each spiked at three concentration levels. The obtained recoveries ranged from 92.3% to 109%, with relative standard deviations below 5.76%, confirming its applicability for real sample analysis. Overall, this study presents an innovative approach for the rapid detection of L. monocytogenes , and provides a convenient tool for food safety monitoring.

The photocatalytic process is a promising, cost-effective, and environmentally friendly method for remediating environmental pollution. Unfortunately, practical applications have been limited by the shortage of highly efficient photocatalysts. To overcome this problem, a unique cactus-like Bi 12 O 17 Br 2 /Bi 2 O 3 /Bi 25 FeO 40 (BBF) was synthesized facilely by hydrolyzing of rod-like MOF (CAU-17/MIL-100(Fe)) precursor, and the ratio of photocatalyst was adjusted by controlling the hydrolysis time. In this photocatalyst, Bi 12 O 17 Br 2 and Bi 25 FeO 40 were dispersed in Bi 2 O 3 , as well as Bi 12 O 17 Br 2 and Bi 2 O 3 were attached to an S-type heterojunction. The developed BBF demonstrated high photocatalytic efficiency and exceptional stability in degrading five bisphenol pollutants. The photocatalytic degradation of bisphenol A (BPA) using BBF could reach up to 98.7% within 60 min under visible light irradiation. Further characterization demonstrated a significant improvement in the photogenerated charge transfer efficiency and confirmed the S-scheme structure of BBF. Additionally, the possible degradation pathways and the evolution of intermediate toxicity of BPA were discussed according to the intermediates detected in the photocatalytic reaction process.

This study introduces a hydrogenated FeCo-MOF derivative catalyst (HC-FeCo@C 350 ) to activate peracetic acid (PAA) for efficient degradation dye wastewater. Rhodamine B (RhB) as a model pollutant, the HC-FeCo@C 350 /PAA achieved a 99.33% removal efficiency within 20 min, with a rate constant 18 times higher than the non-hydrogenated system. Liquid chromatography-mass spectrometry (LC-MS) and the toxicity evaluation software (T.E.S.T.) confirmed reduced intermediate toxicity. Quenching experiments, electron paramagnetic resonance (EPR) tests, and density functional theory (DFT) calculation show that HC-FeCo@C 350 can effectively activate PAA to produce 1 O 2 , CH 3 C(O)O•, and CH 3 C(O)OO•. The magnetically recoverable catalyst maintained over 80% efficiency after 4 cycles. In actual dye wastewater treatment, the RE of chemical oxygen demand (COD), ammonia nitrogen (NH 3 -N), total nitrogen (TN), total phosphorus (TP) could reach approximately 53.57%, 53.23%, 29.25%, 19.2%, respectively, with reduced toxicity validated by mungbean germination experiment. This technology offers a promising approach for refractory dye wastewater treatment and reuse.

Sulfur dioxide (SO 2 ) adsorption, from the exhaust gas of the industrial processes and vehicles, remains an issue due to the corrosive nature of SO 2 . Herein, a novel amino-functionalized bio-derived metal–organic framework, named Bio-ZJU-928(Ni), comprises “paddle-wheel” shaped nickel secondary building unit, acetic acid ligand, and adenine with amino group. It exhibits excellent chemical-thermal stability, specific surface area (634 m 2 g −1 ), outstanding trace SO 2 adsorption (2.94 mmol g −1 ) at 0.002 bar and 273 K, and good cyclical SO 2 adsorption–desorption performance. Bio-ZJU-928(Ni) also has excellent SO 2 selectivity adsorption, identified by its higher ideal adsorption solution theory values for SO 2 /N 2 (32,145) and SO 2 /CO 2 (259.35) at 10/90 ( v/v ) and 273 K, respectively. Under relative humidity (50 %), the dynamic SO 2 adsorption of Bio-ZJU-928(Ni) is 32.47 cm 3 g −1 , which is higher than that of Bio-ZJU-928(Ni) under dry condition (23.08 cm 3 g −1 ) at the mixture gases (N 2 /CO 2 /O 2 /SO 2 = 81.8:15:3:0.2). The enhanced SO 2 adsorption of Bio-ZJU-928(Ni) can be ascribed to the O=S=O···H − O hydrogen bond formed with water, as verified by in situ diffuse reflectance infrared Fourier transform spectroscopy and Grand canonical Monte Carlo simulations

Regulating the separation and transport capabilities of the photocarriers is an important strategy to enhance corresponding activity of photocatalysts. In this work, novel Ti-MOF/Ti 3 C 2 heterojunction with face-to-face intimate contact was design and synthesized through a hydrothermal assemble route. The negatively charged Ti 3 C 2 not only facile the absorb of Ti nodes but also offer rich nucleation sites for the in-situ growth Ti-MOF. Under visible light irradiation, the optimized TM-0.05 exhibited exceptional photocatalytic activity and reusability during tetracycline photocatalytic degradation process. The rate constant reaches 1.83 × 10 −2 min −1 over TM-0.05, which was 5.3 times and 2.3 times higher than that of sole Ti-MOF and Ti 3 C 2 , respectively. Combined photoelectric characterization confirmed the improved photocatalytic activity was predominantly due to the excellent conductivity of Ti 3 C 2 and the tight interface connection between the two semiconductors, thus accelerating the interfacial charge separation and transport. Scavenger experiments, EPR, and LC-MS analysis confirmed the key role of •O 2 - , •OH and photogenerated holes during tetracycline degradation, and finally a possible mechanism was postulated. This work provides a new approach for constructing MOF/MXene structures via in situ self-assembly strategy, and expand their application in refractory pollutants photocatalytic degradation process.

Selective P O bond cleavage in organophosphorus pollutants under acidic conditions represents a key challenge in phosphatase-mimicking nanozyme design. Inspired by natural phosphatases, we designed and synthesized Zr x Co y -ZIF nanozymes featuring a Zr-N 4 coordination framework, achieving alkaline-free detoxification (t 1 / 2 =0.3 min, detoxification efficiency > 99 %). Theoretical analyses reveal that the oxygen-bridged proton shuttle activates interfacial water to supply protons for P O bond cleavage, while the Zr-Co electron transfer system reduces polarization energy barriers, enabling dual-site synergistic catalysis. Additionally, its magnetism facilitates material recovery, ensuring environmental friendliness. Notably, Zr x Co y -ZIF efficiently cleaves phosphodiester bonds and disrupts biofilms, removing > 90 % both Gram-positive and Gram-negative bacteria, with excellent antibacterial effects in real samples (lettuce, chicken, milk; removal rate > 85 %), demonstrating potential as a novel high-efficiency antimicrobial agent.
